The Lowdown
Alright, grab a coffee and sit down, because we’ve got a long stretch ahead. Honestly, right now, Kennebunk Beach is looking pretty flat and sad for the next week and a half. The water is sitting at 66°, which is about normal for this time of year, nothing wild there.
The first few days are all tiny, weak, and messy. Wednesday the 26th through to Saturday the 30th it’s mostly small cross-onshore junk, with swell heights barely scraping 2 ft and the energy is weak (67). Sunday the 30th it drops even more, down to 1.0 ft and 1 ft. That’s a proper flat spell. Monday the 31st and Tuesday September 1st have some glassy or clean moments, but the swell is all but gone, just 1.0 ft at best. You’d be floating and waiting for nothing.
Then there’s a bit of a flicker. Wednesday September 2nd afternoon, the wind turns to light cross-offshore, and we get a bump of 6 ft swell from the ENE, period short at 7 seconds, but the energy jumps to 365. It’s still just surfable, nothing to write home about. Thursday September 3rd is the best of the bunch. Clean conditions with a moderate offshore breeze from the NNE, and the swell holds at 6 ft to 7 ft, from the east, period 8 seconds, and the energy is strong at 944. That’s the standout. It’s not a total classic, but it’s the only window where you’ll get half-decent, clean, head-high-ish waves. That swell is a bit too big for beginners, but fine for intermediates.
After that, it fades again. Friday September 4th drops to 4 ft, and by Saturday September 5th it’s back under 3 ft. The rest of the run into September 10th is mostly small, onshore, and choppy, with a few cleaner bits but no real size. There’s a long gap of poor surf from the start until that Thursday, and then it falls away again.
If you’re a kiter, those Thursday and Friday afternoons with moderate cross-off wind and solid swell might be more interesting than for a surfer. For paddle surfing, you’re really just looking at Thursday September 3rd morning or afternoon as your best shot.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
